Deploy collab like nightly (#7174)

After this change we'll be able to push a tag to github to deploy to
collab.

The advantages of this are that there's no longer a separate step to
first
build the image, and then deploy it.

In the future I'd like to make this happen more automatically (maybe as
part of
bump nightly).
